DRAFT YOKE Application led January'l, 1926. Serial No.- 82,300.

My invention relates to draft yokes einployed` in draft rigging for railway cars. The principal object of the invention isA to {aiiord a draft yoke of simple and easily manufactured form which eificientlv lends 'itself to the application thereto of a rugged and readily replaceable wearing slioe for relieving the yoke of the wear incidentV to its movement with respect to the strap or l0 carrier by which it is 'supported in service.

It is also the object of the invention'to provide a construction whichl not only efciently and reliably performs its principal functions but which minimizes likelihood of breakage of the wearing shoe or the displacement and loss' of the parts of a shoe..

should the latter break while Vin service. vA still further object of the invention is to produce a strong and reliable design of yoke 2o which distinctly suggests the necessity of applying a lwearing shoe thereto, thus reasonably insuring against the shoe being omitted by the car builderor car repairman.

-Anotlier object of the invention is to provide j a form of yoke which is well adapted for being made of cast steel and which may be x finished with the expenditure of little labor vfor cleaning the casting. A ,stillV further object of the invention is to provide a simple 'form of wearing shoe which may in an emergency be easily made from a rectangular piece of metal. Y l

'A primary feature of the invention consists in providing one of the arms of the draft yoke with a plurality of outwardly projecting lugs whichrare spaced from each other longitudinally of the yokeV and lareV adapted 4to engagea wearing shoe for cooperating with the yoke support, the said lugs serving as means :for restraining longitudinal and lateral shifting of the wearing shoe with respect to the yoke.

A further feature of the f invention consists in providing onevof theA arms of the ing in advantageous details of construction and arrangement vof parts will hereinafter appear and be pointed out in the'clainis.-

Figures 15 and 16 are detail views corresponding to Figures 13 and lirespectively.

Figuresl? andlS are respectively a plan Y viewl and a side elevational viewof a modified form ofwearing shoe suitable for use with the yoke shown in Figure 10.

The form of-yoke illustrated in the drawings forthe purpose of explaining the invention is of the quadruple. shear type, its forwardfend being fashioned with an upper 'lug l, a lowervlug 2- and an intermediate lug, each of which is perforatedto receive a pivot pin or'tail pin forconnecting a car coupler thereto.

They upperand lower'ainisyvi and `5 ref spectively, of they draft yoke are spaced apart to receive ya cushioning device (not shown) between them, the rear ends of said arms being rigidly connected by a transversely extending portion which, as shown, is preferably of -beani cross section and may 'be kadvantageously flanged intermediately, as indicatedat7.

Intermediate vits ends the lower arm oi the yoke is integrally formed with la, plu'- `rality of downwardly` projecting lugs 8 which are preferably ot generally rectangu- Ylar cross section and somewhat tapered.

These lugs Vare arranged in pairs, being spaced from each other laterally oit-the yoke arm. A plurality of pairs of lugs 8 are employed, the corresponding lugs oit adjacent pairs being spacedV iroin each other in the direction olength ot the yoke. Vlythis means spaces or recesses are providedL between the lugs i'or receiving intervening portions or the wearing shoe 9 andthe latter maybe assembled with the yoke in sevei'al dierentflocationa thus suiting its po sition to practically any location or yoke support or carrier with which the railway carinay be provided and at the saine time aording it adequate .bearing surface.

The lower face of. the wearing shoe 9 is Vand -so as also to lprovide projecting armsy or portions 13 `and'14 adaptedto intervene lbetween the adjacent ac'es of neighboring lugs 8. `By this means the outwardly projecting lugs upon -the yoke cooperate with the-wearing shoe 9 -so as to-'preventlboth longitudinal and lateral shitting of the shoe with respect to the yoke. The shoulders 1l and 12 of the wearing shoe areprfetcrably Y beveled in correspondence with the tapering lugs 8;.and, as shown in Figures 4t and 5,-

the shoe 9 when made asa casting or forgingmay advantageously be recessed on its upperside in order `to minimize waste ofnietal.. f Thewearing shoe 15 illustrated in Figures 6 and 7 Vis substantially the same as that shown in Figures: t andy 5 except Vthat its upper side is not recessed andaccordingly similar details of construction have been indicated by corresponding vreference numerals. The wearing shoe 16 illustrated in Figures 8 and 9 is of general -H-orm being provided intermediate its ends with oppositely disposed recesses 17 each of which is adapted to receive one of the lugs-8 oic the yoke. When the parts are in assembled re- Y 'lation the walls or shoulders 18 of each oit these recesses is adaptedto engage theopposite sides Vof a cooperating lug 8 while the the` shoe,

intermediate portion 19 of the shoe intervanes between transversely spaced lugs 8 and.. the yend portions '2O of' said shoe are disposed between adjacent longitudinally A spaced lugs.

in themodifiedy form of ai@v investies iilustrated in Figures 10, 1'1 and 12 the lower aiinvof the yoke is integrally fashioned with a series oi' downwardly projecting lugs 21 which' arespaced: `from each lother longitudinally of the yoke and preferably are otconical form. The remaining structural Vfeatures' of this orin; ot yoke are the same as those heretofore described land .accord-y ingly similar parts have beenidentitied by corresponding reference numerals. The lugs 21 .cooperate with a wearing shoe 22 having 'correspondingly tapered openings or recesses for; receiving the lugs 21.` As will be .readily perceived the wearing shoe may be caused to cooperate with the lugs so as to occupy any one of threeditferent positions thus suitino its location to that or' .the

particular support withk whichr the car may be equipped.

frlhe'nioditied oi'ni- Vot shoe 2li shown in..l

Figures-,15 and 16, is identically :the saine as that illustrated in Figures l0, 11, 13 and lt except that the recesses 25 for receiving the lugs21 do not extend entirely Ythrough rThe wearing shoe 267sliow'n; inV Figures 17-and 18, instead othavingflugreceiving openings intermediate its tends, is` y provided with oppositely disposedv open Vsided recesses 27 for receiving adjacent lugs 21 otfthe yoke.v c n f v It rwill` be perceived that my inventionv provides a Wearing shoehavinglonglite in l service and which isfnot* liable to crack,

drop out and beflost.V It will also be perceived that the cooperating parts are Aof such torni that, castingdefects are not apt to be produced in the yoke and-that the lwearing shoes may be readily-,made in case o' an emergency. I claim: 'Y'
